T 0 all whom it may concern:

Be it known that we, CLARE HHDRAPER and JONAS N onrnnor, citizens of theUnited. States, residing at Hopedale, in the county of 'orcester andCommonwealth of Massachusetts, have invented certain new and usefulImprovements in Automatic- Looms; and we do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same.

The present invention relates to an m provement in automatic weftreplenishing looms.

The weft replenishii'ig operation of an automatic loom is generallyinitiated either by a filling t'eeler mechanism or by a filling detectormechanism. A filling feelcr mechanism acts to initiate the weftreplenishing operation when the fillingin the active shuttle has beenunwound or exhaustedto a predetermined extent. Looms controlled byfilling feeler mechanisms are commonly called feeler looms. A fillingdetector mechanism acts to initiate the.weft replenishing operation uponthe breakage or upon the complete exhaustion of the filling. \Vhere itisdesired to weave high grade fabrics on automatic we't'treplenishinglooms, a filling feeler mechanism is employed to initiate thereplenishing operation in order to obviate the presence of mispicks,which are short wefts, and consequently are a blemish in the cloth.There, however, an automatic loom is employed for the sake of weaving agreater quantity of cloth, but of lower grade, the replenishingoperation is initiated by a filling detector mechanism.

In that type of feeler loom in which the weft replenishing mechanism islocated on one side of the loom and the filling feeler mechanism islocated 011 the opposite side of the loom. the filling detectormechanism, (provided on a feeler loom for the purpose of stopping theloo 'n in the event of filling breakage or filling exhaustion), shouldbe location of the located on the replenishing side of the loom if thebest results are to be obtained. The filling detector mechanism. on thereplenishing side of a feeler loom is es sential to obviate mispicksresulting either from an improper filling feeleraction or Specificationof Letters Patent.

from a trailing filling end. If the filling feeler mechanism fails toindicate critical exhaustion of filling at the proper time, the

lling may con'iplctely exhaust before the. shuttle reaches thereplenishing side of the loom. This is liable to result in a inispick,which would not be detected if the detector mechanism were locatedbeside the feeler mechanism. A trailing filling end may be present in afeeler loom for one of two reasons, either because the filling breaks atsome distance from the shuttle, or because the thread parter mechanism,(with which ieelcr looms are provided to sever relatively near theshuttle the filling extending from the fell to the outgoing criticallyexhausted bobbin), operates to sever this filling end when thereplenishing operation has been initiated and its completion preventedby the improper boxing of the shuttle. A trailing filling end resultingfrom either cause may be long enough to extend from the shuttle eye intothe shed when the shuttle is boxed at the filling feeler side of theloom. This is because the shuttle eye is nearer the selvage when theshuttle is boxed at this side of the loom than when it is boxed at thereplenishing side of the loom. It is readily seen, therefore, that ifthe filling detector mechanism were located at the filling feeler sideof the loom, and a trailing filling end were caught in the shed, thefilling fork would be tilted as by a complete filling. and a mispickwould result.

It is frequently desirable to control the weft replenishing operation ofthe same automatic loom both by a filling teeler mechanism and by afilling detector mechanism, the control of the replenishing mechanism atany given time dependingv on the nature of the goods to be woven.Usually only one of the mechanisms will be in operation at one time, forcontrolling the weft replenishing mechanism, that is to say, if a highgrade fabric is to be woven, the filling detector mechanism will beoperatively disconnected from the replenishing, mechanism; whereas, if alower grade of fabric is to be woven, the-filling feeler mechanism willbe disconnected therefrom.

When the replenishing operation is controlled by a filling detectormechanism, a

misthreading device is preferably provided,

. CLARE H. DRAPER AND JONAS NORTHROP, or HOPEDALE, MASSACHUSETTS,assronons ANY, or MILronn, MASSACHUSETTS, A con to act in conjunction"with the detector mechanism. It is the function oi threading device. topermit the replenishing mechanism, when the shuttle does not lay fillingin the shed, to attempt for a predcter mined number of times to restorenormal weaving conditions; and it' it fails within that number of timesto properly thread the shuttle, to stop the loom.

I So tar as is known it has not hitherto been proposed to provide afeeler loom, havingthe teeler mechanism on one side of the loom and theweft replenishing and filling detector mechanisms on the opposite sideof the loom, with a misthrading device, and particularly in which thelatter is located on the filling teeler side of the loom and controlledin its operations by the tilling detector mechanism. Accordingly, oneobject of the present invention is to produce a misthreading device ofsuch construction that it may he applied to a filling feeler controlled,automatic loom provided with a filling detector located on thereplenishing side of the loom, so that the loom may he op erated eitheras a feeler controlled or as a misthreading de'vice controlled automaticloom.

Another object of the-invention is to produce a misthreading device ofsuch construction that it may he applied to a feeler loom having thefilling detector mechanism located on the same side of the loom'with thereplenishing mechanism, and the filling i'eeler mechanism located on theopposite side of the loom so that the loom may be operated either as afeeder controlled or as a misthreading device controlled loom.

Another 0b ect of the invention is to produce a misthreading device ofsuch construction that it, may be applied to the filling teeler side ofa teeler loom of the type in which the filling. detector mechanism isloeat/ed on the replenishing side of the loom and the filling feelermechanism is located on the opposite side of the loom, so that the loommay operate either as a filling feeler controlled or as a misthreadingdevice controlled automatie loom.

A further obgectof the invention 1s to provide an auton'iatic loomhaving a single filling detector mechanism, and that located on the weftreplenishing side o1 the loom, with a misthreading device of suchconstruction that it; will operate to cause loom stoipage on theoccurrence of more than inisthread.

.' A further object of the invention is to provide an automatic loomhaving a single filling; detector mechanism, and that located on theweft replenishing side of the loom, withainisthreading device mechanismof such construction that it may he located on the opposite side of theloom and be controlled in its operations by the detector mechanism. v

A still further object of the invention is a miss to produce amisthreadiin device having provision tor causing loom stoppage on theoccurrence of either two real misthreads or two hopper misthreads.

To the accomplishment of the ohjccts above set "forth, and such othersas shall hereinafter appear, the invention consists in the automaticloom having the improved features described in the t'ollowin;specification and particularly pointed out in the appended claims.

The preferred form of the invention is illustrated in the accompanyingdrawings, in which Figures and l" are plan views of parts of theopposite ends of a teeler loom showing the application oi themisthreading device oi the present invention ta the 'loom; Fig, 2 is asectional view showing in siddelevation the misthrezuling device; Fig.is a detail view showing the relative positions of the actuating camstor the weft hammers; Fig. l is an enlarged view of the knock-oiltumbler and tumbler controller of the misthrcading device looking fromthe left in Fig. 1: Fig. 5 shows in perspective views the positionsassumed by the various parts of the misthreading device during a normaloperation of the weft replenishing mechanism; and Fig. (3 shows inperspective views the positions assumed by the various parts of theinisthrcading device on the occurrence of two misthreads. certain partsof the misth'readine' device being left out in positions "2 to 5inclusive.

Before describing the construction and node of ope ation of themisthreadinp; device, it will conducc to a clearer understanding' of theinvention to premise a "few general remarks concerning' the "arrangewardbeat of the lay utter replenishinent.

The necessity for the, operation of the. thread parter mechanism at thistime will he set forth later. In cooperation with the niechanismsmentioned are two weft hammers located on opposite sides of the loom:the

'wcft hammer cooperating with the filling d tor mechanism acts to stopthe loom on hlling absence, and the weft hammer co-- operating with thefilling lreler mechanism acts to initiate the weft replenishing:operation. The nnsthreading device oi the; i

"anisi'n to control its movements. in mind that the function of themisthreadassesses present invention then must be of such constructionthat when it is appli'edto an automatic loom having the cotiperatingmechanisms above enumerated, and the filling side of the loom, althoughit may be otherwise located, so. that it may act directly on the samelatch lever through which the fill mg feeier mechanism causes anactuation of the weft replenishing mechanism.

We have then, a feeler loom of the type described in which the fillingfeeler mocha;-

msm is assumed to be held inoperative.

Under such circumstances the loom may be regarded as a non-feeler loom.In this loom the misthreading device is located on one sideof the loom,and on the opposite or replenishing side is a filling detector mech-Bearing .ing device is to permit the replenishing neChanism to attemptfor a predetermined number of times to restore normal weaving, and thatit is applied to a loom in which the weft hammer cooperating with thefilling detector acted only to stop the loom when the loom operated as afeeler loom,

' and that the other weft hammer unconnected, operatively or otherwise,with the detector mechanism acted only to initiate the replenishingoperation, that is, to lift the usual transferrer latch into the path ofits hunter on the lay, it will be understood that the beat up of the layon which filling absome is first detected does not initiatereplenishment, but that this initiation takes place on the next beat-up;

filling absence indication on the replenishing beat must be renderedineffective,-otl1erwise we should have two successive replenishingoperatioiis, whether or not the first was successful. And accordingly,provision is made. in themisthreading device of the present invention tonullify'this second fillthe shipper or knock-off lever 38 pivoted at ingabsence indication so that no operation consequently the replenishingoperation does not take place '"nntilthe second forward of thereplenishing mechanism will result therefrom. .And in like manner, if amisthread occurs and there is a second replenishing operation, thedetection of filling absence on this detecting beat will also benullified. It is thus seen that a series of four'successive beat-ups ofthe lay inter-- venes between the first .and second operations of thereplenishing mechanism.

The loom shown in the illustrated embodiment of theinvention' isprovided at one side with a Weft replenishing mechanism, the hopper ofwhich is indicated at 10, and at the opposite side with a fillingfeelermechanisn'l. generally indicated at 12. Any usual or preferredform of filling feeler mechanism may be employed. That shown in thedrawin'gs comprises a feeler member or lever 13 pivoted at 14 on a stand15 fastened on a bracket 16 projecting outwardly from the end of thebreast beam 17. The feeler lever 13 is articulated by means of a link 18With'a latch lever 19 pivotally connected with a lever 20 pivoted at 21to an arm secured to a hollow rock or change shaft 23 journaled inbrackets on the front of the breast beam and connected at the other sideof the loom with the weft replenishing mechanism. The rear end 24 of thelever 20 is freely supported for sliding movements. The latch lever 19is pivoted at 25 on the rear end of the lever 20 and has a notched end26 which, when the filling has been. exhausted to a predeterminedextent, is adapted to be moved by a spring 27 interposed between thelatch lever and the adjacent side of the lever 20 into the path of itscooperating weft hammer 2S pivoted at 29 on the loom frame and to beengaged thereby on the forward beat of the latter to push forward thelever :20 to oscillate the change shaft and thereby initiate the weftreplenishing operation.

lVhen the loom operates as a feeler loom, as has just been described, itis usual to stop it in the event of breakage or complete exhaustion ofthe filling, and for this purpose in the loom of the present invention afilling detector mechanism is located on the weft replenishing side ofthe loom. This detector mechanism comprisesa filling fork 30 pivoted inthe usual manner on a detector slide 31 mounted for sliding moven'ientsin a bracket 32 secured to the breast beam. Vihen filling is absent, thefilling fork 30 is not tilted and its tail 3% remains in the path ofmotion of its cooperating wef hammer 35, so that the slide 31 is pus ledforward; and in so doing it moves outwardly the arm 36 secured to therock for stop shaft 37 fulcrumed at the front of the breast beam in thehollow change shaft 23, oscillating the stop shaft and, throughmechanism presently to be described, causes ceeding beatup ot' the lay.

While the looin is thus operating as a teeler controlled replenishingloom, the misthreading device of the present invention is heldinoperative, except to cause loom stoppage. and when the loom is tooperate as a misthreading device controlled replenishing loom, thefilling teeler mechanism is held inoperative and the n'iisthreadingdevice is put into operative connection with the latch lever 19 so as tocontrol the movements of the replenishing mechanism through the lever20.

The parts of the misthreading device of the present invention areadapted to be actuated by the two weft hammers bet'ore mentioned, whichare located on opposite sides of the loom. The wetthammer located on thesame side of the loom with the misthreading device is adapted when thenotched end of the latch lever is in its path of motion, to initiate theweft replenishing operation. Incidentally, this weft hammer operates toreturn certain parts of the misthrcading' device in normal position. Thewelt hammer located on the replenishing side of the loom is adapted onfilling absence to move the detector slide 31 for ard and therebythrough the'arm 36. the rock shaft 37, and an arm :3, to actuate themisthreading device. This wet't hammer is further adapted, on the.occurrence of a predetermined number of successive filling absences. to.cause the anisthrcading device to actuate the shipper lever to knockotl' the shipper and thereby stop the loom. For the sake. ofconvenience. the weft hammer which initiates the replenishing operationwill be termed the lett-hand weft hammer, and the weft hammer whichactuates the misthreading device on filling: absence will be termed theright-hand weft hammer.

As a prerequisite to a clear understanding of the operation of themisthreading device and its etlect upon the loom operation, it will benecessary to consider the movements oi the'lay with relation to themovements of the two weft. hanmers. When the shuttle has made a flightacross the lay, the lay moves forward so that the reed may engage thefilling lei't in the shed by the shuttle and beat it up against the tellof the woven cloth. While the lay is substantially on its front center,supposing the shuttle to have been boxed at the right-hand side of theloom, the rig'htdiand weft hammer will begin its forward movement, andit filling has been laid in the shed by the shuttle, the filling forkwill be tilted and the right-hand Weft hammer will i'noveforward withoutcooperating with the filling fork. \Vhile the right-hand weft hammer ismoving forward, the left-hand weft hammer moving rearwardly, and by thetime these weft hammers have reached the limit of their respectivemovements, the lay has again beaten backward to permit the shuttle to bepicked to the opposite side of the loom. The la v will then move forwardagain, and when it is substantially on its for 'ard center, theright-hand weft hammer will begin its rearward movement and theleft-hand weft han'rmer will begin its forward movement. It will beobserved that while the lay is beating forward, both weft hammers remainpracti ally quiescent. The. weft hammers are caused to move thusalternately with each other, and in their timed relation with themovements of the lay by the relative positions of their respectiveactuating cams. The actuating cam for the left-hand weft hammer is shownin full lines in Fig. 3, and the actuating cam for the right-hand wetthammer is shown in the dot and dash lines. Cam followers 30 connect theweft hammers 'with their respective actuating cams.

The misthreading device of the present invention operates to cause loomstoppage on the occurrence either of two hopper misthreads or two realmisthreads. A. hopper misthread occurs during; the weft replenishingoperation. and results in an absence of filling on the first tlig'htofthe shuttle away from the replenishing mechanism. A real misthrcadoccurs by reason of the filling failing to enter the shuttle eye, inintact filling being laid in the shed on the first flight of the shuttleaway from the replenishing mechanism, and in an absence of filling inthe shed on the-first return. flight of the shuttle to the replenishing-Slut. of the loom. Inasmuch as the filling detector mechanism in theloom of the present inven tion is located on the replenishing side ofthe loom, it will be observed that the absence of filling resultingIrorn a. hopper misthread is not detected until the second forward beatof the lay after replenishment; and in like manner the absence offilling resulting from a real misthread also dctected on thesecondforward beat of the lay after replenishnrnit. Consequently, so tar thedetection of filling absence resulting from misthreads is concerned, ahopper misthread shows the same symptoms as a real misthread, and,accordingly, it will not be necessary throughout the descriptive portionof the specification to distin-v guish between the two ltindsotmisthreatls,

and resultsone real misthread, or vice versa. In other' but it will besufficient for a clear understanding'of the operation of themisthreading device to designate them both by the term misthread.

The improved misthreading device comprises ingeneral a knock-off memberor tumbler 45, a knock-off tumbler controller 46, and a latch levercontroller 47. The

1. knock-01f member or tumbler i5 is adapted to be brought intoengagement-with the end -18 of the knock-ofi' lever 38 to knock off theshipper on the occurrence of either two hopper misthreads, or two realmisthreads, or on the occurrence of one hopper misthread and words, theknock-oil tumbler is adapted to actuate the knock-off lever on theoccurrence 1 of two misthreads: An enlarged view of the knock-offtumbler is shown in Fig. 4. It is provided on its under side with aseries of knock-off lever engaging teeth 49, 50'

and 5-1. 'When either of .the teeth 49 or 50 engages the knock-01flever, an actuation of "the tumbler cannot result. inan actuation of theknock-off lever. But when the tooth 51 isin engagement with the knock-01f lever, and the tumbler ismoved forward by the tumbler controller,the knock-01f lever is actuated and the loom is stopped. The knock-offtumbler is adapted to be controlled in its movements by the tumblercontroller 46, an enlarged view of which is shown in Fig. 4. The tumblercontroller 46 is provided with a straight under part, and is looselymounted for sliding movements in agroove in a bracket secured to thebreast beam. The tumbler controller 46 is pivotally connected at itsforward end with the upper end of the arm 43 secured to the stop shaft37, the oscillatory movements of which are imparted to it by the fillingdetector mechanism through the arm 36.

When on the occurrence of an effective filling absence, that is, thefirst of every two completes its forward movement alone. But

when the tooth 51 of the tumbler is in engagement with the end of theknock-off lever, and the tumbler is. moved forward, which is the case onthe occurrence of two luisthreads, the tumbler is carried forward by thetumbler controller and actuates the knock-off lever. For the purpose ofcarrying the tumbler forward far enough to actuate the knock-off lever,the tumbler controller is provided with an upright 53 which engages aknock-off lug 54 projecting laterally from the tumblen. Until thepredetermined number of misthreads have occurred, the position of thetumbler relatively to the tumbler controller is such that the upright 53does not engage the knock-01f lug; but when the requisite number ofmisthreads have occurred, the position of the tumbler relatively tothetumbler controller is such that the knock-oft lugpresses against theforward side of the upright 53, and the tumbler may 'be moved forward bythe tumbler controller without relative movement thereto.

The knock-off tumbler is held in operative engagement with the tumblercontroller by its weight alone, so that it may move longitudinally andvertically relatively thereto, and for this purpose it is provided withtwo bearing lugs 56 and 57 which are sharp angled on their undersides.The bearing lug 56 is adapted to rest either on ,the surface 58 on theforward end of the tumbler controller, or in the notches 59' and 60,while the bearing lug 57 is adapted to rest in the notches 62, 63 or 64.During normal operation of the loom, when the partsvof the misthreadingdevice are in normal position, the bearing lug 56 rests on the. surface58 and the bearing lug 57 restsin the notch 62, as shown in Fig. 2. Whena single effective filling absence has occurred, due either to fillingbreakage or complete exhaustion of the filling during'normal weavin thelug 56 is received 'in thenotch 59,-wh1le the lug 57 is received in thenotch 63, as shown in position-1 of Fig. 5. When a-single misthread hasoccurred, which. is the second effective filling absence, the lug 56occupies the notch 60 while the lug 57 occupies. thenotch 64 as shown inposition 1 of Fig. 6. At this time the knock-off lug 54 presses againstthe upright 53, so that on the occurrence of a second 'misthread orthird suc- 1L0 cessive effective filling absence, the loom may bestopped. The latch lever controller 47 is pivotally mounted at 66 on anupright projection 67 rising from the rear end of the bracket 55, andextends forwardly with its free end nor mally resting on the uppersurface of the lever 20. It -.is the function of the latch levercontroller to hold the latch lever in inoperative position during normalweaving and to permit it to swing into operative position in the path ofthe left-hand weft hammer on the indication of first filling absence, oron the indication of a misthread. For the purpose of holding the latchlever in inoperative position during normal weaving, the forward end ofthe latch lever controller flares laterally outwardly at 68, as'shown inFig. l, and the edge of this head 68 is adapted to engage with a stoplug 69 rising from the forward the two. lf ,"-follo\\'in asinglemisthread end of the latclrleven \Vhen on the forthe shuttle is propeily threaded. normal ward movement of the tumbler controller 46, weavingconditions are resumed: but if two due to the forward movement of thedetecmistln-cads occur in siiccessi( ii,,tlie loom is tor slide 31 onthe indication of effective stopped. filling absence, the upper surfaceof a cam The operation of the misthreading devicelug 70 projecting from'the upright 53 laterduring a normal operation of the weft really towardthe latch lever controller, comes plenishing mechanism will bedescribedin into engagement with the under surface of connection withFig. only, which shows the a lug 71 projecting from the. forward endvarious positionsassumed by the. parts of 7 of the latch levercontroller laterally tothe misthreading device on the successive wardthe upright 53. it thereby lifts the forforward beats of the lay.

The engagement of thetwo lugs during the rearward movement of thetumbler controller causestherearward endof the tumbler cont-roller to be lifted out of'its guidingslot, as shown in position 2. I After passing over the lug -71, thelug'70 passes on to the upper surface of a lug 74 projecting laterallytoward the tumbler con f troller from the rearward end of the lever 20.This lug 74 on the rearward end of the lever 20 is for the purpose ofpreventing the tumbler from descending into its normal position at thistime. It will beseen by reference to position 1 that while the lever 20is in normal position, before the left-hand weft hammer has movedforward, the lug 74 is to the rear of the lug 71*, and that thelowermost point of the lug 74-IlS in the plane'of the uppermost point ofthe lug 71, and that, consequently,-'when the lever 20 has been movedforward by the left-hand weft- .hammer and the lug 74 has been movedinto 50 engagement with the lug 71, the two consti-- tutea continuoussurface upon which the In 70 is adapted to slide.- This arrangement'oparts is provided, because it will be understood that if the tumblercontroller were permitted to' assume its normal position. at this timewith its lug 70 to therear of the. lug 71, the next forward movement ofthe tumbler controller would again raise the forward end oft-he latchlever controller and permit the latch lever to assume its operativeposition in the path of the left-hand weft hammer, so as thereby toeffect a raising of the transferrer latch, which would result in theinsertion of another filled bob- J5 bin in the shuttle before it wasdetermined ,tion' 2 to the the-tooth 50 on thetumbler passed over the{forced-I against the lever 'edntroller,

-We have thus far had two beat ups of the lay, the first, on which theabsence of H filling Was detected, during which the latch lever wasoperativel ositioned in the path of the left-hand we t iammer, and thesec ond, during which the latch lever was engaged by the-left-hand wefthammer and moved forward to position the transferrer latch in the pathof its hunter. The lay now beats forward for the third time, and duringthis beat-up the replenishing operation takes place and a new supply offilling a is inserted in the shuttle. On this replenishing beat-up ofthe lay, the right-hand weft hammer again engages with the fork'tail,

because of fillingabsence, and again moves forward the-detector slide tocause an os- :5 summ r the stop rock shaft '37 and a forwardmove-merit'of thetmnblercontroller. As the tumbler controller movesoutwardly, its lug slides down over the two lugs 7t and 71 so as toassume a position in front of s the latch controller lug 71, as shown inposttion 3 While the tumblercont ller was descending m'fthefpositibn'shown in posiposltionshown in position 3.

end rs-30f the knock-off lever anddid not engage therewith, so thatthere was no relative movement between thetumblerand the tumblercontrollen Consequently, the bean ing lugs 56 and '57 still .remain inthe notches 59 and 63 respectively, into which notches they Werereceivedon the first outward movement. ofthe tumbler controller;

'It is seen, therefore, that this second outward movement of the tumblercontroller had no effect whatever upon the, relative positions of theparts of the misthreading device. While the'jtumbler and the tumblercontroller were moving outwardly, with the, forwardfmovement of theright-handweft 11L hammer, the left-hand 'weft' hammer was,retreating-and. the lever 20 was returning toward thefbreast beam,During'this', 1rear-- ward movement 'of the lever 20, the'stoplugj, 69on the forward end of the latch leverwas cam. surface 72 .o'fTth head'68; 5911. the'forward end of the latch A and the latch love thembyeaused to'swing on its pivot notchedend to be forced out of the pa' oftheileft-hand weft hammer Whilex't parts of'the misthreading devicehave. 1 assumi'n the positions shown in position 3," the lay itsretreated and the shuttle has;-

- Upon the fourth beat-up of'the lay, the]? 5 right-hand weft hanuner'retujrns -and th e-" left-hand weft hammer moves forward. A

the right-hand weft hammer is moving rearwardly, the tumbler controllerperforms a corresponding rearward movement, and the under surface of thelug is forced against the upper surface of the lug 71, so that thetun'lbler controller with the tumbler is again the positionshown inposition t. j By thistime the left-hand weft hammer has come forwardsufficiently far, so that as the tumbier controller and the tumbler aredescending. the rear end of the tumbler descends on top of agbunter 76.secured to the lefthand weft hammer. It will be observed that by reasonof these movements the tooth 50 of the tumbler is positioned rearwardlyof the end 48 of the knock-off lever. During this last forward movementof the left-hand weft hammer and the rearward movement of theright-handw'eft hammer, the lay has beaten backward and the shuttle has beenpicked t'o-the replenishing side of the loom.

The lay nowmoves-forward on the fifth successive beat-up, and inasmuchas the assumption is that the shuttle was properly threaded during thereplenishingoperation, the filling will be present and the filling forkwill be tilted, so that there will be no cooperation between theright-hand weft hammer and the fork tail; consequently, the detectorslide will remain quiescent, and so will the tumbler controller. It willbe borne in mind that in order. that the filling detector mechanism mayindicate-presence or absence of filling on this beat-up of the lay-, itn-as'necessary for the incoming filling end tot have been previouslyevered. It is assumed that the incoming filling-end was severed by theparter mechanism. 41 during the first beat-up of the'lay afterreplenishment. \Vhilc the right-hand weft hammer was moving forward atthe completion of the fifth beat-up of the lay, the left-hand wefthammer was performing its correspondingrearward movement. This rearwardmovementof. the left-hand weft hammer disengaged the hunter 76 thereonfrom under the rear end ofthe tumbler, which thereupon descended untilits bearing la 57 was again received in the notch 63. The

'positions of the various parts of the mistbreading device at thecompletion of these movements is shown in position 5; \Vhilethesedescribed movements have been taking place, the lay hasagainretreated and the shuttle has been boxed a't the filling feelerside of the loom.

The lay now moves forward on its sixth successive beat-up, and then theleft-hand weft hammer beats forward and the righthand weft hammer movesrearwardly. It 4 will be observed from an inspection of position 5 thatat this time the rear-end (5 of the tumbler is in the path of motion ofthe banter 76. Consequently, as the hunter 76 is moved forward with theleft-hand weft hammer, it strikes the rear end of the tumbler, therebyforcing. the bearing lugsfit and 57 to .travel up the inclined forwardsurfaces of the notches 59 and 63 respectively.

The range ofmovement of the hunter 76 is such th'atthe tumblerJspushedforward 'untilthe front bearing lu 5G is on the surface 58 on theforward on of the tumbler controller, and the rear bearing lug. 57occupies the notch. (32. lVhile the hunter was thus resetting thetumbler, the teeth on the under side thereof did not 'enga e with theend -28 of the knock-off lever, cause of the arrangement and inclinationoaths forward surfaces ofthe notches 59-and 63.. The parts of themisthreading device are now in normal position, and normalweavingconditions have been restored.

The operation of the :misthreading device on the ioccurrence of twomisthreads will be desci'ibeil with reference to Fig. 6'

in connection with Fig. 5. The positions assumed by the misthreadingdevice on the first four beat-ups of the lay on the occurrence of twomisthreads, are identical with the positions assumed by the misthreadingdevice on the first four beat-ups ofthe lay during normal-replenishment. To recapitulate these -movements briefly:

' ()n the first beat-up filling absence resulting from either fillingbreakage or from complete exhaustion was detected. The parts ofthe-misthreading .device then moved from their normal position to thatshown in position 1 ofFig. 5. On the next forward beat of the lay, theparts of the -misv misthread has occurred due either to a breakage ofthe filling during the replenishposition on its fifth beat-up. It isassumed that a ing operation or to a breakage of the filling on thereturn shot of the shuttle to the replenishing side because thefillingfailed to enter the shuttle e e. As a result filling will be absent onthis fifth beat-up of the :lay, the filling fork will not be tilted andthe fork tail will be engaged-by the righthand weft hammer on itscorrespondingforward movement. The detector slide will therefore bemoved forward, and this will result in the forward movement of thetumbler controller. It will be. observed by reference to position 4 ofFig. 5 that the tooth 50 on the under side of the tumbler is behind theend '48 of the knock-off lever. Consequently, when the tumblercontroller is moved forward, due to the detection of filling absence,the tooth 50 will be drawn against the end 48 of the knock-off lever,and the tumbler will .be held thereby while I the tumbler controllerlcompletes its out- ;lugs 56 and 57 will be ward movement.v Thereplpptrhthe bezfiriplg i out o t e notches 59'and 63 arid-will be received intheafiiotches 60 and 64' respectively. While the tumbler'con'troller wasmoving forward, the upper side'of its lug 70 engaged with,

.the. under side of the latch controller lug 71 and lifted. the forwardend of the latch controller as before to permit the notched end of thelatch lever to assume its operative position in the path of'theleft-hand weft hammer; The position of the parts .atfthe completion 0these movements is shown in position 1 of Fig. 6. The difieiw encebetween the action of the misthread i ing device as shown in position 5of Fig. 5 and the action of the misthreading device asshown in position1 of Fig. 6, is duet o the fact that in position 5 of Fig. 5 fillingpresence was indicated by the de' tector mechanism, and the tumblercontroller remained quiescent; whereas in the latter-case fillingabsence was detected and the tumbler controller was moved forward. Inthe former case, while the. right-hand weft hammer was moving forward,the tum;

- bler controller remained quiescent,-so that as the left-hand wefthammer was moving rearwardly, the bearing lug- 57 descended into thenotch 63, In the latter case, while the left-hand wefthammer isreturning, the

tumbler controller is moving forward and the bearing lug 57 does notdescend into the notch 63, but into the notch 64. During thesemovements, the lay has moved picked 1.. bind the latc the left-hand wefthammer is moving f01' ward, the. right-hand weft hammer is returning,thereby permittin the -tumbler control-ler to move rearwar dly.'Thisrearward movement ofthe tumbler controller again brings the undersurface bf its lug into engagement with the upper surface of the latchcontroller lug 71, so that as the tumbler controller continues itsrearward movement, its lug 70 travels up the inclined surface of the lug71. As before, the forward move: ment of the lever 20 brought its In 7 4immediately behind the latch eontro ler lug so as to afford a rest forthe tumbler controller lug in order to prevent the tumbler controller Infrom assuming a. sition be of the parts at the completion of thesemovements 1S Sl10WIl in position 20f Fig. 5 with the exception that thetumbler and tumbler controller occupy the; relative positions showninposition 2 0f1Fi Z 6. Wlule these movements were taking p ace, thelayhad controller--lug.'==- heposition retreated and the shuttleli ad beenpicked, I

to the replenishing side of thef loom.

, 'The'lay. now movesforwardfonl-its seventh beat np, which is areplenishing beat. It

remembered that'lthe first-beat' detected filling absence, that thethirdboat was a ireplenishmg beat, andthatthe fifth beat detected the absencecaused by -the misthread; the seventh beat accordingly is a replenishingbeat, and the fillii' 1 will of course be absent, and as the'right andweft hammer moves forward on its." rres nding beat, it will engage thefoi k tai and move forward the detector slide, which will.

result in the forward movement of the turn-- 'bler controller. Thetumbler controller lug will again slide down over the lugs 71 and 74without raisin the forward end of the latch lever controller; and thetumbler-will pass over the-end 48 of the knock-off lever withoutengaging therewitlr VVlnle the tumbler controller was moving forwardly.synchonously with the right-hand weft hammer, thelever 20 was movingrearwardly,

synchronously with the left-hand Weft hammer, and consequently the stoplug on the forward end of the latch lever was again forced against thecam surface of the head 68 on the forward end of the latch levercontroller and the latch lever was turned on its, pivot untilitsvnotched endwas moved out of the path of movement of the left-handweft hammer. Upon the completion of these movements, the parts of themisthreading device occupy the positions shown in position 3 of Fig. 5,with the exception that the tumbler and the tumbler controller arelocated relatively-"to each other, as shown i in position 3 of Fig. 6;and also with the nously with the retreat of the right-hand weft hammerthe tumbler controller moves rearwardly, and as it. does so the undersurface of its lug 70 engages with the upper surface of the latchcontroller lug 71, whereby the tumber controller is caused to moveupwardly; By'this time the left-hand weft hammer has moved its bunterinto the path of the downward movement of the rear end of the tumbler,anduconsequently the real' end of the tumbler is received on the uppe r'surface of the hunter 76. inasmuch at} the latch lever was heldinoperative by thehead 68, the lever 20 was not moved for. ward. As aresult the lug 74 on the rear end thereof stood fast, which permittedthe tumbler controller lug to fall behind. the latch controller lug, andthe tumbler controller to assume its normal position. The positions-ofthe parts upon the completion -of these movements is asshown in position4 of Fig. .5, except that the tumbler and tumbler controller are relatedshown in position 4 of Fig. .6. It will be observed that at this timethe tooth 51 is behind the end 48 of the knock-off lever and that theknock-off lug 54 presses against the front side of the upright 53. Whilethese movements were taking place, the lay had retreated and the shuttlehad been picked to the replenishing side of the loom'. It isassumed-that during the secondr 'ilenishing operation another misthreadoccurred. that is. either the thread broke during the replenishingoperation, or else the thread did not properly enter the shuttle eye andwas broken on the flight of the shuttle toward the replenishing side.Consequently, the filling will be absent on the next detecting eat.

The lay now moves forward on its ninth successive beat-up, and on theassumption that filling is absent, the right-hand weft hammer on itscorresponding forward movement will engage with the fork, tail an'd moveforward the detector slide, and consequently the tumbler controller. Theforward movement of the tumbler controller forces the upright 53 againstthe knock-off ingot the tumbler, which forces the tooth 51 OftlIG'klIOCk-Ofi tumbler against the end 48 of th e knock-off lever,causing the knock-off starts up the loom again, he will usually catchthe end of the filling in the temple. It will not be necessary,therefore, to have a replenishing operation, and accordingly the notchedend of the latch lever'must'be moved into inoperativeposition. For ,thispurpose a pin 78 rises vertically from the knock-011' lever, and as thisend of the knock- -ofi' lever is moved outwardly-bythe engage- 'm'ent ofthe knock-oil tumbler therewith, the

pin 78 is brought-into engagement with a cam lug 90 pro]eetingfromtheforward end of the latch lever into the path of motion of the pin 78.The outward movement of this pin in engagementwith the lug 90 causes thelatch lever to be swung on-its pivot, so as to permit the head 68 on theforward end of the latch lever to descend to engage with the stop lugand hold the latch lever in inoperative position. The loom will now'bestarted without a replenishing operation taking place until the fillingis a ain broken or completely exhausted. By reason ofthe'cooperativeaction between the pin 78 and cam lug 90, so long as the shipper is off,the loom can be freely turned by hand without an operation of thereplenishing mechanism. This is of, special advantage in matching pickswlien the loom is operating as 'a feeler loom on -y.

The operation of the misthreading device permitting the loom to run, ifafter the occurrence of one misthread the replenishing mechanismsucceeds in properly threading the shuttle, will be readilyunderstood'from a consideration of "position 4 of Fig. 6 in connectionwith position 4 of Fig. 5. '-It will be observed that position 4 of Fig.6 represents the position of the parts after the lay hasmoved forward onits eighth beat. If

it be assumed that during the second replenishing operation the shuttlewas properly threaded, the succeeding or ninth beat-up of the lay wouldtherefore find filling resent, and consequently the right-hand we thammer would not cooperate with the fork tail,

and the detector slide and the tumbler controller would remain qiiescent. It will be furthereobscrved that the positions of the parts ofthe misthreading device at this time (at the completion of the ninthbeatup) mt-mam i a. i.

would correspond exactly to the positions of I picked to the fillingfeeler side of the loom,

and on its next forward movement and the corresponding forward movementof the left-hand weft hammer, the bunter 76 thereon would engage withthe rear end of the knock-oft tumbler and return it to its normalposition (as will clearly appear from a consideration of Fig. 4), inexactly the same.

manner in which it is returned to normal posit-ion, as described inconnection with the operation of the misthreading device during normaloperation of the weft replenishing mechanism.

It is thus seen that when normal replenish ment takes place, the partsof the misthreading device are returned tovnormal position in sixdieatsof the lay, and that when two misthrcads occur, the loom is stopped onthe ninth beat-up of the lay; and further, that when only one misthreadoccurs, the parts of the misthreading device are returned to normalposition on the tenth forward beat of the lay. l l

Itwill be understood that by increasing the number of teeth on theforward under side of the knock-off tumbler and by increasing the twosets of'notches on,the tumbler controller correspondingly, themisthreading device may be made to effect loom stoppage on theoccurrence of any predetermined number of misthreads.

When afeeler loom of the type described is provided with a misthreadingdevice of the presentinvention, and the weft replenishing mechanism isto be controlled in its operation by the filling feeler mechanism alone,the misthreading device will be rendered inoperative by holding theforward end of. the latch lever controller lifted by inserting a cotterpin in the hole 82 thereof, so that the head 68 on the latch lever controller will not engage with the stop lu 69 on the latch lever. Theknock-off tum ler will then be moved into position so that its tooth 51will be to the rear of the end 48 of the knockoff lever and the bunter76 on the left-hand weft hammer will be lowered so that it will notengage with the end 75 of the tumbler. The filling feeler mechanismhaving been put into operative condition, an occurrence of fillingabsence and a corresponding forward .movement of the detector slide 31will result as beforein a forward movement of the tumbler controller,which will cause the tooth 51 of the tumbler to engage with and actuatethe knock-off lever to lUi'K'k oil the shipper and stop the loom.

It will now be apparent from the foregoing description that the objectsof the invention have been accomplished and that the following novelfeatures of automatic loom construction'have been produced: First, anautomatic loom havin a weft'replenishing mechanism, a single Hingdetector mecha-. nism, and a thread parting mechanism, all. located onthe same side of the loom, has
